Remove flag_friend_activity_access_api() and extend flag_friend_activity_info()

This will break flag_friend. To fix do this:

/**
 * Implementation of hook_activity_info().
 */
function flag_friend_activity_info() {
  flag = flag_get_flag('friend');
  $info = new stdClass();
  $info->api = 2;
  $info->name = 'flag_friend';
  $info->object_type = 'flag_friend';
  $info->objects = array('requestor' => 'user', 'requestee' => 'flag_friend'); // array keys are the labels
  $info->hooks = array('flag_friend' => array('approve', 'request', 'deny', 'remove'));
  $info->realms = array('flag_friend' => $flag->title);
  return $info;
}
